Teorijo, da povzročajo človeški izpusti toplogrednih plinov globalno ogrevanje – po novem “podnebne spremembe” – je znanstveno razvrednotila že sama narava: podnebje se je (celo bolj) ogrevalo v prvi polovici 20. stoletja[i], kljub bistveno manjšim človeškim izpustom CO2; in še bolj v daljni preteklosti, npr. med Srednjeveškim toplim obdobjem[ii]. Domnevno antropogeno ogrevanje s konca 20. stoletja se je že leta 1995 ustavilo, od leta 2002 pa se ozračje ohlaja[iii] - kljub temu, da človeški izpusti in zračna koncentracija CO2 še vedno rastejo. V nasprotju z napovedmi Medvladne komisije za podnebne spremembe (IPCC) led na Grenlandiji[iv], Arktiki[v] [vi] in Antarktiki[vii] narašča, prav tako praktično vsi kontinentalni ledeniki[viii], morje se ohlaja[ix] in gladina se ne dviguje[x] [xi]. Ampak, prav v letu pred podnebnim vrhom v Cancunu je pričela teorija o antropogenem ogrevanju izgubljati tudi politično podporo. [Originalne reference na koncu zapisa]
"while the globe has nominally warmed since 1995, it is difficult to establish the statistical significance of that warming given the short nature of the time interval (1995-present) involved. The warming trend consequently doesn’t quite achieve statistical significance. But it is extremely difficult to establish a statistically significant trend over a time interval as short as 15 years"
"For the measurement of this extent, it doesn’t matter at all how thick the ice is: any ice, however thin, contributes to sea-ice extent. Therefore, only considering a possible “recovery” of just the extent of Arctic sea ice always remains somewhat superficial, since sea-ice extent contains no information on the thickness of the ice."
Antarctic sea ice extent continues to show interannual variability and localised changes but no statistically significant average trends, consistent with the lack of warming reflected in atmospheric temperatures averaged across the region.
Assessments of Antarctic temperature change have emphasized the contrast between strong warming of the Antarctic Peninsula and slight cooling of the Antarctic continental interior in recent decades. ... This picture, however, is substantially incomplete owing to the sparseness and short duration of the observations. Here we show that significant warming extends well beyond the Antarctic Peninsula to cover most of West Antarctica, an area of warming much larger than previously reported. West Antarctic warming exceeds 0.1 °C per decade over the past 50 years, and is strongest in winter and spring.
I came to the realization that intelligent design, as a theory of origins, is no more religious, and no less scientific, than evolutionism. ... True evolution, in the macro-sense, has never been observed, only inferred. ...If the public school system insists on teaching evolution as a theory of origins, in the view of many a religious activity, why is it discriminating against the only other theory of origins, intelligent design?
Once he has a proper paper outlining exactly what was done, and how the known issues have been dealt with, we might be in a better position to judge - but for now, this is merely curious, not definitive.
A large (~10^23J) multi-decadal globally averaged warming signal in the upper 300 m of the world’s oceans was reported roughly a decade ago and is attributed to warming associated with anthropogenic greenhouse gases. The majority of the Earth’s total energy uptake during recent decades has occurred in the upper ocean, but the underlying uncertainties in ocean warming are unclear. ...Accounting for multiple sources of uncertainty, a composite of several OHCA curves using different XBT bias corrections still yields a statistically significant linear warming trend for 1993–2008.
